current value. Press the 1 and 0 keys to enter 10 A.

Enter Enters the 10 A value, then displays WIDTH B = X.XMS. You're being

prompted for the duration of the 10 A load -- press the 1 and 0 key for 10

ms.

Enter Enters the 10 ms duration, then displays :CONTINUOUS, :PULSE, or

:TOGGLED. Use the △ or ▽ arrow keys to display :PULSE.

Enter Returns to the standard display of voltage and current.

To activate this pulse transient condition, press Shift + Tran, then press On/Off. The load will start

at the A level of current you entered (5 A). Press Shift + Trigger to cause the load to switch to the

B level of current (10 A). The 10 A current will last for the designated 10 ms, then switch back to the

A level (5 A).

NOTE: This example requires the :CONFIG:TRIGGER menu item be set to :IMMEDIATE. If set

to :EXTERNAL, you'd trigger the instrument with a high TTL level signal on the trigger terminals on

the rear panel. If set to :BUS, you'd trigger the instrument with a software trigger.

Toggled transient operation

In toggled transient operation, the load starts at the stored parameter for the mode. When a trigger

is received, the load switches to the B value. When another trigger is received, the load switches to

the A value. It stays at the A value until another trigger is received, at which point it switches to the

B value. Further triggers cause the load to switch between the A and B values. Here's an example:
